i had following problem asset pipeline. i have html email image inside. i have tests covering case in email sent successfully. all tests pass. when going production, feature requiring email sent broken, because html layout referencing non existent image. this applies precompiled assets. it seems me tests no longer reliable. there way avoid situation happen again? i found perfect solution form own case. if set config.assets.compile = false config.assets.digest = true in test environment, tests rely on precompiled assets. since annoying precompile assets every time during quick development , testing phases, in case it's enough have configuration on ci only. you can setup initializer called ci_config.rb following: if env['ci'] class yourapp::application config.assets.compile = false config.assets.digest = true end end and configure ci run rake assets:precompile on start , rake assets:clean on end.

i think found reproducable bug in visual studio. when try adding "testcontrol" project, visual studio crashes. maybe it's fault, , i'm doing wrong. build, , add control form: here's project (11kb): https://www.dropbox.com/s/dk62j347zmwbll8/visualstudiocrash.zip i haven't included binary files. if want test it, build , add "testcontrol" form. if somehow manage, click on control , see if crashes then. thanks help. the cause obvious: public string description { { return description; } set { // lbldescription.text = value; } } you're making recursive call accessor description property. visual studio going infinite loop when place control on designer.

i have code , want show customers respective card numbers,, 1 of customers associated cards of cards table.. what's wrong?? in advance select `customers.idcustomer`, `customers.emri`, `customers.mbiemri`, `customers.kontakt`, `customers.vendbanimi`, `customers.adresa`, `customers.email1`, `customers.tel1`, `xts_cards.card_no`, `xts_cards.card_type`, xts_cards.mer_id customers inner join `xts_cards` on `customers.idcustomer` = `xts_cards.mer_id_owned_by`

in project need select 1 row values using linq try { return database.employees.where(x => id.equals(x.id)).single(); } catch (invalidoperationexception ix) { throw; } using corresponding row values through entity object.but throwing error if result set empty.the problem in project exception must logged. how can manage code out going exception. you're using single() documented throw exception if there no results. if don't want behaviour, don't use method :) if use singleordefault() return null if there no results. still throw exception if there multiple results, however. alternatively use firstordefault avoid this. note can specify predicate in single / singleordefault well, don't need where call first: return database.employees.singleordefault(x => id.equals(x.id));

assume 1 of many developers working git on huge code project, has incredibly long compilation time . now, personal day-to-day changes limited, , codebase decently modular, means far personal work concerned, compiling scratch price has paid once . afterwards, can recompile modules modified. on other hand, i have fix bugs in (at least two) branches reflect states of codebase distinct branch work on . 2 branches indeed result of work entire development team, , have entire modules rewritten or added. having compiled before pushing bugfix mandatory . my first approach switch development branch every time bugfix needed, clean, bugfix, recompile scratch, push, switch original branch, clean again, recompile - the delay doing intolerable . i moved keeping 3 separate checkouts of codebase on machine . solves " costly recompilation " problem (my changes in every branch incremental again), makes question "what developing on right ?" more complex answer (since depe...

currently have .pem file containing private key. need convert file .pkcs12 file. i'm trying use openssl achieve , i'm running problems. the .pem file i'm using of form: -----begin rsa private key----- some key -----end rsa private key----- i use following openssl command attempt convert .pem file .pkcs12: openssl pkcs12 -export -inkey file.pem -out file.p12 the console hangs message: loading 'screen' random state -done what im doing wrong? any appriciated. i ran problem , resolved adding -nocerts option after export. guess regarding cause of "freeze up" openssl trying read additional input console. openssl pkcs12 -export -nocerts -inkey your.private.key.pem -out your.private.key.p12

i'm working on web site show kind image gallery on detail pages. must show navigation @ bottom small thumbnail images , must show per each element basic information , big image. the big image must resized too, because there maximun size allowed them. the point use source image per multimedia component , being able resize images on publishing time so, source image sent client browser thumbnail , big image. it's possible show small , big images using styles or html, quite uneficient because source (some of them heavy) image sent customer. my first thought custom code fragment, written in c# find complicated resize images size , resize them again size too. don't find way replace src on final html appropiate paths neither. another idea create old-style publishbinary method find complex because looks current tridion architecture not meant @ all... and important point, in case can resizing succesfully (somehow) it's tridion 2011 issue publish twice same image. b...

i have obtained certificate trusted authority (have been given .pfx file). i signed .jar files jarsigner this: jarsigner -storetype pkcs12 -keystore my_pfx_file.pfx -storepass my_store_pwd -signedjar smy_jar.jar my_jar.jar then exported certificate keystore create .cer file. what else have don't message "unknown publisher" , instead has company name? i figured out. problem .pfx file. see certificate chain in mmc console, when used: keytool -list -storetype pkcs12 -keystore my_pfx_file.pfx , saw certificate chain length 1. so exported certificate mmc console. time, check box says "include certificates in certification path if possible". got new .pfx file signed jars , works perfectly. post helped me lot figure out going on: how sign java applet .pfx file?

i'm using k-means clustering group set of news items. i'm using bag-of-words model represent documents, more specifically, each document represented term frequency vector. my question: how can add new documents without having recalculate term frequency vectors (seen vocabulary containing terms docs change)? the easy solution use vocabulary documents you've seen, ignoring new terms; customary in document classification. another solution, that's become popular in recent years, ditch vocabulary altogether , use feature hashing . a third possibility reserve space in feature vectors future terms. e.g., let's you're vectorizing bunch of documents vocabulary of size n , turn them vectors of size n + k final k set zero, can add k terms vocabulary later on. (what not solution compute dot products, means, etc. on hash tables directly. flexible approach, it's very slow.)

are created incrementally? integers, i'm wondering if generated in particular way. knowing useful me application writing. edit: need keep in memory ids , thinking if can order them able search. if created increasing number easy implement search binary search, that's why asking the thing can find in documentation pertaining id following excerpt: id ( integer ) id of tab. tab ids unique within browser session. so can glean no 2 tabs ever same id in same session. there's no information in docs how they're generated. ultimately think approach predictive in sense doomed bugs & failure, should building responsive application vs. predictive one. instead of assuming next tab opened id # 12, capture creation of tab, you'll know id , can perform operations based on that. what need tab oncreated event . when tab created you'll tab object can tabid , windowid , perform whatever actions desire. since didn't tell ultimate goal, can...
